On a day when starting outfielders Carlos Gonzalez and Dexter Fowler both suffered injuries that have them listed as day-to-day, the Rockies received the biggest blow when All-Star shortstop Troy Tulowitzki went down with a broken rib. The injury, which Tulowitzki had been dealing with in recent weeks and which he aggravated diving for a ball in Thursday's loss to the Nationals, will most likely keep him out 4-to-6 weeks.

Injury is nothing new to Tulowitzki. The shortstop played in only 47 games in 2012 due to a groin injury, and he's had seasons of 101 and 122 games played in recent years as well.

The Rockies will likely call up Josh Rutledge when they place Tulowitzki on the disabled list Friday, but replacing his production will be impossible. In 61 games this year, Tulowitzki is hitting .347/.413/.635 with 16 home runs and 51 RBI.

Replacing a shortstop is one thing. Replacing a player having an MVP-type first half is quite another.

Rising Price

While one big star is expected to miss significant time, another may miss less significant time than originally anticipated.

David Price, who hasn't pitched since May 15 with a strained triceps muscle, was expected to need around three rehab starts in the coming weeks before returning to the Rays. But after Thursday's 54-pitch bullpen session, that timetable may be "accelerated," according to Rays manager Joe Maddon.

"He's actually exceeding expectations a little bit," Maddon told MLB.com. "I thought he could have pitched today in an actual game. He's accelerated; there's no question. I just have to sit down and talk with everybody before I give you guys bad information. I just saw a guy who was a lot further along than we thought."

He's expected to begin a rehab assignment next week, meaning he could be back with the club before the end of June. And while he wasn't his usual dominant self through the first six weeks of the season, a return to form could quickly follow once he proves to be healthy.

Hart Still On The Mend

Just a little more time is all he's asking for.

Brewers general manager Doug Melvin said Thursday that Corey Hart, who hasn't played yet this year as he recovers from knee surgery, now may not be back until after the All-Star break.

It was originally thought Hart may be able to return close to the beginning of June, but that timetable had been pushed back as he continued to slowly progress in his recovery. Hart has been running the bases but has yet to run at full speed, a prerequisite before talks of a rehab assignment can begin. It now seems that his knee is shaky enough to require some extra time to heal before trying to push it.

It's certainly a blow to fantasy owners who have had a DL spot occupied by Hart for over two months, but the Brewers offense is the biggest loser in this news. Heading into Friday's games, the Brewers have gotten a .183/.222/.280 line with four home runs from the first base position this season. Pedestrians such as Yuniesky Betancourt, Alex Gonzalez and, currently, Juan Francisco have manned the position in Hart's absence.

If there's one thing we've learned, though, it's that even if his rehab takes longer than expected, Hart still will never surrender.

The Rockies sustained plenty of injury on Thursday. All the Nationals had to do was take care of the insult.
